- Kansas City still feels Mathieu's legacy from its 2019 Super Bowl run to today.
As the Chiefs in 2019 were converging on their first Super Bowl in 50 years, something typically intangible took virtually palpable form in their locker room: the chemistry that bubbles up from a thriving culture.
Winning tends to mask or mend fissures in any group, of course.
But this was about something more than a late-season winning streak or evidence of purging the defensive albatross threatening to undermine the promise of the advent of Patrick Mahomes.
It was about a living, breathing vibe and the dynamic catalyst who kindled the potential:
Safety Tyrann Mathieu, the rare sort of person capable of connecting with and energizing anyone in his considerable sphere of influence … and who retired Tuesday at age 33.
It was one thing for Mathieu to be a first-team All-Pro that season. And it was another that he could uplift young defensive backs like corner Charvarius Ward and then-rookie safety Juan Thornhill with his work ethic, encouragement and even constructive criticism.
“When he walks in the room, like, everything lights up,” Ward said by his locker early in the season.
But it was something else that he radiated such light it carried with clarity all around a room of diverse personalities.
Gazing toward Mathieu diagonally across the room in December 2019, receiver Sammy Watkins considered how Mathieu’s spirit resonated.
“It’s something that you can feel …” he said. “It’s just something he’s been called to do. I can feel his energy everywhere.”
The same could be said for coaches and fans and those who’ve been aided by his charitable work …. And, yes, even those of us in the media.
In nearly 40 years in the business, I don’t believe I’ve ever covered a player more consistently engaging, accessible, accountable and illuminating.
Enough so that he could spur entire column ideas from casual chats in the locker room and that he was eager to participate in a 2020 Star Facebook Live forum on sports and race moderated by Blair Kerkhoff.
More than that, though, he was a constant source of points of inspiration and contemplation even for an interviewer.
“Being a great teammate, it might be better than being the best player on the team,” he said one day as we spoke one-on-one at his locker.
What a beautiful thought.
And what an example he set in every way, from his relentless play to his back story of what he overcame to his foundation work … to his fundamental role in launching a dynasty.
No wonder Mathieu’s surprise retirement announcement from his hometown New Orleans Saint reverberated here even three years after the Chiefs let him go in a business move that left him “heartbroken,” as he put it to The Star’s Sam McDowell.
But the mere numbers that decision was based on never could measure his impact, both back then and, really, ever since.
As Sam reported last year before the Chiefs played the Saints, Mathieu not only set a tone but established standards and ways that have endured.
So a moment after he was asked about Mathieu on Wednesday, day two of the Chiefs’ training camp at Missouri Western, defensive coordinator Steve Spagnuolo tapped his heart about five times and called him a “special, special guy.”
“I love Tyrann Mathieu …” he said. “He’ll do something great going forward. He might end up being the president, who knows?”
He’ll definitely end up being present in the hearts of those he’s touched here almost since the moment the Chiefs signed him as a free agent in 2019 a few weeks after Spagnuolo had replaced Bob Sutton.
Just like a coaching friend had predicted when he gave Spagnuolo a scouting report of sorts on Mathieu.
“‘He changed the building the minute he walked through the door,’” Spagnuolo in 2019 recalled the friend saying.
That he did, by hosting teammates in his home on Thursday nights and putting together video clips for them to learn from and taking ownership of his own mistakes, etc.
To say nothing of what he taught us all by being willing to share his story and immediately pouring himself into his new community — he reached out to then-mayor Sly James soon after signing to see how he could help.
And with such deeds as spending 20 minutes in a freezer to raise awareness of the danger of leaving dogs outside in the winter cold.
All stuff befitting the Chiefs 2021 nominee for the NFL’s Walter Payton Man of the Year award.
In his retirement announcement on social media, Mathieu thanked those who’d believed in him for “giving me strength when I needed it most, and your love carried me farther than I ever imagined.”
He thanked the game itself for giving him “purpose, discipline and memories that will stay with me forever. But more than anything, it gave a community.”More than anything to the rest of us, it gave him a platform I’ve seldom seen used to more positively indelible effect and that we can all thank him for.
As a three-time All-Pro and member of the NFL’s all-decade team for the 2010s, Mathieu has the makings of a fine Pro Football Hall of Fame case when he becomes eligible in five years.
But the case to be made is deeper and more meaningful than those surface accolades.
It’s about the truest of hearts and souls.
Something he brought to life not just on the field or in that locker room scene in the fall of 2019 but that also has been sustaining ever since he came through here for anyone lucky enough to have been around him.
